摘要：Digital Watermarking is an encryption technique that protects the ownership of multimedia using algorithms. It has opened a new domain in multimedia security and protection against attacks. In this paper, an experiment is conducted using four inputs images. In order to propose a Multi-Watermarking method using four inputs we have applied an inductive computation that improved the quality of output image from one side; and robustness of trademarks which are extracted from the process on the other side. The process contains four two dimensional trademarks which will be converted and combined into a three dimensional sequence. The next phase is to use sub-digital images in Discrete Wavelet Transform domain and decompose them into non-overlapping blocks and finding the block which contains the most densely packed information pertaining to texture (based on the size of the binary image). The latest stage is to embed the final Multi- Watermark before adjusting the selected block pixels. This will be based on some discrete operation rules, which will later be discussed. The results will be compared to currently available three-input methods.
